I agree those prices are incomprehensible. There is nothing great about
them at those prices.
Before MS discontinued them, they were one of the most comfortable,
non-fatiguing, and accurate input devices available, and their demise
is sad. I certainly would not buy one at those prices.
I have two which I have had for about 8 years now. I also bought one of
the very affordable ($30) Logitech Trackman Wheels, which is fine, but
lacks a few of the features of the MS Trackball.
